初识AS3（十）——加载外部文件进度…

=================外部图片或swf加载进度===================
CODE:

//加载外部图片jpg（gif）或影片swf

var url:String = "http://qzgzs.51.net/temp/images/d2.jpg";

var loaderoader = new Loader();

pzztq(loader.contentLoaderInfo);

var dizhi:URLRequest = new URLRequest(url);

loader.load(dizhi);

addChild(loader);

//申明一些变量

var jd:Sprite=new Sprite();

var xzb:Number=stage.stageWidth/2-50;

var yzb:Number=stage.stageHeight/2-1.5;

var jindubj:Sprite=new Sprite();

var jinduk:Sprite=new Sprite();
